The Euler-Langrange equation for the quantized skyrmion is derived. It modifies the static properties of the nucleon and it admits rotation and vibration coupling which should improve the baryon spectrum. The pi NN form factor from the Skyrme model is used to calculate the high energy PP scattering in the Chou-Yang model. Several projects on the lattice gauge Monte Carlo calculations are completed. The pion form factor is measured in both the relative charge distribution method and the symmetric source method. The vector and pseudoscalar meson decay constants are measured in the lattice QCD. The vacuum to glueball transition matrix elements are extracted to calculate the glueball branching ratios in J/psi radiative decays. The result helps identify theta (1720) as the tensor glueball. By combining data anti pn annihilation and gamma gamma reactions, we have pinned down that X/sub 0/(1480) which decays to rho/sup 0/rho/sup 0/ is the mesonium we predicted. By postulating tensor meson dominance in the energy momentum tensor couplings, we obtain the vacuum to glueball transition amplitudes which agree with those extracted from the lattice to within a factor of 2. The branching ratio of theta (1720) in J/psi radiative decay is thus calculated which agrees with the experimental data. We have developed an extended Skyrme interaction which not only yields good Hartree-Fock ground states of spherical nuclei, but also predict electric and magnetic excitations which agree with experiments. Initial investigation on the particle-particle seems to show that the calculated /sup 18/O spectrum is desirable.
